Description

Centurion Arms LLC is happy to announce the C4 MLOK® rail. C4 MLOK 12in FSP (For Carbine Gas FSB's)

The MLOK C4 rail system is based off the patented quad rail version. It is a lightweight, rugged, 2-piece free float rail that when installed gives the uppers a continuous 12o’clock rail and MLOK slots for the 3,6, and 9 o’clock positions. The C4 system is the lightest and most rigid rail that clamps to a standard barrel nut on all AR15, M4, and M16 type weapons systems. This design allows the installation of the rail on an upper assembly without removing the front sight post or permanently attached muzzle devices.

5 of 5 STAR "Best Centurion Arms Rail yet!" March 2020

Best Centurion Arms Rail yet!

I installed a C4 MLOK FSB rail this weekend on an old Colt 6920 that had been relegated to the back of my safe.   The lightweight nature of this rail, impeccable build quality, and flexibility afforded by the MLOK slots and extended FSB rail completely transformed my old carbine.  I could not be more pleased.   And as always, Centurion Arms customer service was second to none.  This is the best Centurion Arms rail yet.
